While water is known to exist on Mars, most is found in the planet’s cold polar regions as ice. Typically water ice is not found exposed at the surface near the equator, as temperatures there are not cold enough for exposed water ice to be stable. Minerals seen in this part of Mars typically contain only a few percent water, much less than is evidenced by these new observations. “We found a central part of Valles Marineris to be packed full of water – far more water than we expected. This is very much like Earth’s permafrost regions, where water ice permanently persists under dry soil because of the constant low temperatures,” told one of the scientists involved in the study.
These are very inspiring discoveries for the future human colonization of Valles Marineris region we have imagined in our speculative Mars Colonization Timeline!
⇧ In the area C up to 40% of the near-surface material appears to be composed of water (by weight).
The most water-rich area in Valles Marineris region is located in Candor Chaos:

Over the years planetary scientist, the director of Haughton-Mars Project, Pascal Lee has created a set of paintings depicting human mission to the Martian moons Phobos and Deimos. Here are several of them. More of his Mars related paintings
